Sub $350 3D printer, a first look at the all-in-one HP Envy PC, and a self-watering Chia Pet system.


Starting 3D Printer        
-- Tracy Delph        
"Hey guys, I'm looking to buy my first 3d printer. My price point is sub $350. I've watched the KnowHow episode for the MonoPrice Maker Select and the New Matter Mod-t. I like both of these printers but I've seen some posts saying the Mod-t is more of a toy than a good 3D printer. Any recommendations, I'm new to this category but I catch on pretty quick. Thanks in advance..."

Help me fix my dead NAS!        
-- Hagos Rush        
"I live in Long Island, NY. We had a storm. The power flickered on/off numerous times. My APC battery backup didn't kick in and my 12TB LaCie NAS died. I am unable to get to the web interface at all. This is my only backup.

Here is what I need:
1. Affordable but good battery backup
2. If I get another NAS and drop the drives in...Am I up a creek? Or is there hope?
3. Is there a way to manually connect to the drive (not networked)?"        
* LaCie NASs don't have SSH        
* Look are your router LAN table to see if it's getting an address (shows that the network IS up, but the UI is not avail        
* Power on, pull drives, reinsert, let it sit FOR A WEEK.        
1. UPS Problem        
-- There are two types of UPS "Online" and "Standby"        
  * In a Standby UPS, you're running on utility power until disrupted, then it switches to battery and inverter        
  * In an Online UPS, you're running on battery and inverter, which is charged by utility power        
** Online tends to be more expensive, less efficient (b/c you're always charging)        
*** There is a relatively NEW UPS, called "Delta Switching" in which SOME power is provided by battery and some by utility.        
2. No guarantee of the drives working        
3. No        
3Dumb Routers        
-- Tod Sage        
"Did any router manufacturers ever put the 3 dumb router principal concept into practice in a single hardware package?"
